Specifications

1 Cooling Requirements

Motorola VMEmodules are specified, designed, and tested to operate reliably with an incoming air temperature range from 0 degrees C to 55 degrees C (32 degrees F to 131 degrees F) with forced air cooling.

Temperature qualification is performed in a standard Motorola MVME900 series chassis. Twenty-five watt load boards are inserted in the two card slots, one on each side, adjacent to the board under test to simulate a high power density system configuration. An assembly of three axial fans, rated at 71 CFM per fan, is placed directly under the MVME card cage. The incoming air temperature is measured between the fan assembly and the card cage where the incoming airstream first encounters the module under test.

Test software is executed as the module is subjected to ambient temperature variations. Case temperatures of critical, high power density integrated circuits are monitored to ensure component vendor specifications are not exceeded.

While the exact amount of airflow required for cooling depends on the ambient air temperature and the type, number, and location of boards and other heat sources, adequate cooling can usually be achieved with 5 CFM flowing over the module. Less air flow is required to cool the module in environments having lower maximum ambients.

Under more favorable thermal conditions it may be possible to operate the module reliably at higher than 55 degrees C with increased air flow. It is important to note that there are several factors, in addition to the rated CFM of the air mover, which determine the actual volume of air flowing over a module.

FCC Compliance

The MVME712-10 transition board was tested in an FCC-compliant chassis, and meets the requirements for Class A equipment. FCC compliance was achieved under the following conditions:

❏ Shielded cables on all external I/O ports.

❏ Cable shields connected to earth ground via metal shell connectors bonded to a conductive module front panel.

❏ Conductive chassis rails connected to earth ground. This provides the path for connecting shields to earth ground.

❏ Front panel screws properly tightened.

(14)

General Information

1

For minimum RF emissions, it is essential that the conditions above be implemented; failure to do so could compromise the FCC compliance of the equipment containing the modules.

General Description

The MVME712-10 Transition Module is a low-cost I/O transition board for MotorolaÕs MVME166 Single Board Computer VMEmodules and their peripheral devices. Refer to Figure 1-1.

The MVME712-10 routes the signals to the appropriate industry standard connectors on its front panel. This board can be mounted either next to the MVME166 or in the back of the chassis. The board contains four shielded 8-pin RJ45 jacks for EIA-232-D serial interface, a shielded DB-15 connector for Ethernet, and a shielded DB-25 connector for parallel interface.

The MVME712-10 also provides conversion from the 68-pin high-density SCSI connector to a standard 50-pin low-density SCSI connector.

Each EIA-232-D serial port transmits the following signals:

❏ Data carrier detect

❏ Request to send

❏ Transmit data

❏ Receive data

❏ Clear to send

❏ Data terminal ready

Cables Required

The following cables are needed in order to connect the MVME712-10 to the MVME166 and other devices:

❏ One 100-conductor, 25 mil pitch cable to connect the MVME712-10 to the MVME166 for I/O (a 1-foot-long cable is furnished by Motorola).

❏ One 68-conductor, 25 mil pitch P cable to connect the SCSI port on the MVME712-10 to the SCSI port on the MVME166 (a 1-foot-long cable is furnished by Motorola).

MVME712-10 Module Preparation

Serial Port Configuration 2

The four RJ45 EIA-232-D serial ports are factory configured as terminal (DTE) for connection to modem. However, they can be used as modem-to-terminal (DCE) by using an appropriate user-supplied external DCE adapter.

Serial Port DCE Configuration

Figure 2-2 shows the schematic representation of the DCE configuration of serial ports 1 through 4, using a user-supplied external DCE adapter.

Serial Port DTE Configuration

Figure 2-3 shows the schematic representation of the DTE configuration of serial ports 1 through 4, using a user-supplied external DTE adapter.

Configuration Register

Figure 2-4 illustrates the function of the configuration register on the MVME712-10. The application software on the MVME166 can read the configuration information to identify the transition board(s) in the system.

On the MVME166, the MC68230 interrupt level is the same as the CD2401. The interrupt vector is as programmed in the MC68230. The interrupt priority is (1) first the CD2401, and (2) then the MC68230.

To read the configuration information, the MC68230 (PI/T) must be programmed as follows:

❏ Port A direction must be:

Ð Mode 0, submode 1X Ð Bits 7 to 4 as inputs Ð Bits 3 to 0 as outputs.

❏ Port B direction must be:

Ð Mode 0, submode 1X Ð Bit 7 as an output Ð Bits 6 to 0 as inputs

Write port B bits 7 to 0 set configuration mode. Now port A bits 3 to 0 are used to select a port.

(20)

Introduction

This chapter provides the interconnection signals, parts lists with parts location illustrations, and schematic diagrams for the MVME712-10 Transition Module.

Manual Terminology

An asterisk (*) following the signal name for signals which are level significant denotes that the signal is true or valid when the signal is low.

An asterisk (*) following the signal name for signals which are edge significant denotes that actions initiated by that signal occur on high to low transition.

Interconnect Signals

80-pin connectors J1 through J4 on the MVME712-10 correspond to the RJ45 EIA-232-D serial ports on the MVME712-10 front panel.

J5 and J7 are identical 50-pin connectors for low-density 8-bit-wide SCSI cable (one is accessible from the front and one from the back of the board) and are connected internally to J6, a high-density 16-bit-wide SCSI connector for the P cable. Connector J6 is cabled to connector J8 on the MVME166.

C ^aution

J8 is a 25-pin connector for the printer port, and J10 is a 15-pin connector for the Ethernet interface.

J9 is a 100-pin connector that is cabled to connector J9 on the MVME166 SBC for I/O.

All front panel connectors have metal shells and jack posts that are electrically connected to the front panel. If the front panel is electrically connected to the chassis ground then the shells and jack posts are connected to chassis ground.

This allows shielded cable to be used for effective reduction of EMI and RFI problems.
